Application filed December 13, 1926. Serial No. 154,444.

The present invention is designed to simplify foot bolts making anefficient structure of this type that may be very inexpensivelyproduced. Features and details of the invention will appear from thespecification and claims.

The invention is illustrated in the accompanying drawings as followsFig. 1 shows a perspective view of the bolt in place on a door.

Fig. 2 a sectional view of the bolt on the line 2-2 in Fig. 3.

Fig. 3 a front elevation of the bolt.

1 marks the door, 2 the floor, and 3 a bolt socket in the floor. Thefoot bolt has a back plate 4 formed of a piece of strap steel. The backplate is secured to the door by screws 4 extending through perforationsin the back plate. The back plate has an out-turned lower end 5 with abolt guide opening 6 therein. A bolt 7 extends through the opening 6 andis adapted to be received by the socket 3. A bolt extension 8 extendsthrough a bolt opening 9 in an out-turned upper end 10. The bolt has afoot shoulder 11 formed by bending the bolt extension.

A spring 12 is in the form of a loop, the ends of the loop being securedunder fingers 13 which are struck up from the metal of 0 the back plate.The spring engages the bolt frictionally and with sufficient force tore' tain the bolt in its elevated or lowered position.

A retracting lever supporting loop 14 is formed in the back plate andhas bolt openings 15 in the end, portions of the loop through which thebolt extension extends.

The bolt has aslot 1.6 into which a retracting lever 17 projects. Theretracting lever extends through an opening in the outer face of theloop 14- and is pivotally mounted on a pin 19 carried by cars 20 at thesides of the opening 18, these cars being formed of metal struck up fromthe face of the loop and from that portion of the loop in which theopening is formed. The retracting lever has a corrugated extension 21which may be readily engaged by the foot to retract the bolt.

The bolt can be readily forced into latching position by pressure on theshoulder 11, or retracted by pressure in the retracting lever in theusual manner. Among the outstanding features of this structure are itssimplicity and cheapness.

WVhat I claim as new is 1. In a foot bolt for doors, the combination ofa back plate having an out'turned lower end, said lower end having aguide opening therein and an outward projection above the out-turnedlower end, said projection having a boltopening therein and a retractinglever opening therein; a bolt in the guide and bolt openings; and aretracting lever engaging the bolt extending through the retractinglever opening and pivotally secured on the projection.

2. In a foot bolt for doors, the combination of a back plate having anout-turned lower end, said lower end having a guide opening therein andan out-turned loop above the lower end having bolt openings in thebottom and top walls of the loop and a retracting lever opening in theface of the loop with outwardly extending cars at the edge of saidlast-mentioned opening; and a retracting lever engaging the boltextending through the retracting lever opening and pivotally securedbetween the ears.

3. In a foot bolt for doors, the combination of a back plate havinganout-turned lower end, said lower end having a guide opening thereinand an outward projection above the out-turned lower end, saidprojection having a bolt opening therein anda. retracting lever openingin the projection, said back plate also having spring retaining fingersstruck up therefrom; a bolt in the guide and bolt openings; a retractinglever engaging the bolt extending through the retracting leveljopeningand pivotally secured on the projection; and a spring in the form of aloop frictionally engaging the bolt having its ends extending under thespring securing fingers.

In testimony whereof I have hereunto set my hand. 1
